The lab of superconducting metamaterials was created at National University of Science and Technology "MISIS" in November 2011 under the mega-grant of Russian government. The topic of mega-grant: “Superconducting metamaterials: development of superconducting structures with unique electromagnetic features and analysis of their physical properties”.
The main field of lab’s work is an experimental research of electromagnetic features of superconducting metamaterials in the range of ultrahigh rates with a usage of one-dimensional and two-dimensional structures.

MONTH OF POSTDOCS LECTURES 2016

29 March 2016

In the framework of MONTH OF POSTDOCS LECTURES 2016 PhD Ben Hamida Aymen and his scientific advisor Prof. Valery Ryazanov will give the lectures introducing their joint scientific work in the laboratory for superconducting metamaterials.

Lectures will be held on 18th of May, between 15:00 and 17:00, library.

To realize novel elements of superconducting electronics and spintronics based on hybrid nano- and microstructures, a Josephson magnetic memory based on Josephson superconductor/ferromagnet/superconductor junction (SFS junction) is fabricated and investigated [1,2]. The first successful experiment detecting a perceptible supercurrent in an SFS structure was carried out in 1999 [3]. An application of small external magnetic field changes the magnetization of the ferromagnetic layer that in turn changes the junction critical current Ic, allowing the realization of two distinct states with high and low Ic, corresponding to logical “0” and “1” states, respectively.

In this lecture, a quick review of Josephson magnetic memories will be given as well as new results on multilayered Josephson SIsFS structures, with a tunneling barrier (I) and a thin superconducting layer (s), namely Nb-Al/AlOx-Nb-Pd0.99Fe0.01-Nb junctions.
